How to fix?

Upgrade Rocky-Linux:8 python-wheel to version 1:0.31.1-3.module+el8.5.0+671+195e4563 or higher.
This issue was patched in RLSA-2021:4151.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-wheel package and not the python-wheel package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:8 relevant fixed versions and status.

This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the _punctuation_re regex operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.
